From: Martensitic transformation of Ti50(Ni50−xCux) and Ni50(Ti50−xZrx) shape-memory alloys
Dependency of the energy differences between austenite and martensite ΔE for (a) Ti50(Ni50−xCux) and (b) Ni50(Ti50−xZrx) on doped content (0–25 at.%). (c) Composition dependence of ΔE and transformation temperature Tm of Ti50(Ni50−xCux) and Ni50(Ti50−xZrx) alloys. The values of Tm refer to the right axis and those of ΔE to the left axis. Tm of Ni-Ti-Cu is cited from refs16,35, Tm of Ni-Ti-Zr is cited from refs10,13. Lines are guides for the eyes.
